Dame Zaha Mohammad Hadid (Arabic: زها حديد Zahā Ḥadīd; 31 October 1950 – 31 March 2016) was an Iraqi-British architect, artist and designer, recognised as a major figure in architecture of the late-20th and early-21st centuries. Born in Baghdad, Iraq, Hadid studied mathematics as an undergraduate and then enrolled at the Architectural Association School of Architecture in 1972. In search of an alternative system to traditional architectural drawing, and influenced by Suprematism and the Russian avant-garde, Hadid adopted painting as a design tool and abstraction as an investigative principle to "reinvestigate the aborted and untested experiments of Modernism [...] to unveil new fields of building."

She was described by The Guardian as the "Queen of the curve", who "liberated architectural geometry, giving it a whole new expressive identity". Her major works include the London Aquatics Centre for the 2012 Olympics, the Broad Art Museum, Rome's MAXXI Museum, and the Guangzhou Opera House. Some of her awards have been presented posthumously, including the statuette for the 2017 Brit Awards. Several of her buildings were still under construction at the time of her death, including the Daxing International Airport in Beijing, and the Al Wakrah Stadium (now Al Janoub) in Qatar, a venue for the 2022 FIFA World Cup.

Hadid was the first woman to receive the Pritzker Architecture Prize, in 2004. She received the UK's most prestigious architectural award, the Stirling Prize, in 2010 and 2011. In 2012, she was made a Dame by Elizabeth II for services to architecture, and in February 2016, the month preceding her death, she became the first woman to be individually awarded the Royal Gold Medal from the Royal Institute of British Architects (Ray Eames and Sheila O'Donnell had previously been awarded it jointly with Charles Eames and John Tuomey respectively).
